Multiblock copolymers represent a fascinating class of materials that sits at the very heart of industrial applications and fundamental polymer science. They are most often made of a linear succession of incompatible “soft” and “hard” segments that microphase separate at room temperature while they can be easily re-homogenized upon heating. This thermoreversible character provides them with decisive advantages with respect to other rubber-based materials such as vulcanized elastomers, making them indispensable for the development of a more sustainable polymer industry. Beyond practical opportunities, tailoring the multiblock copolymers morphology has a pivotal role to play in the fundamental understanding of the structure–properties relationship of polymer-based systems. It notably serves to comprehend complex materials such as semicrystalline homopolymers and nanocomposites. Aside from the thorough work developed on well-defined diblock copolymers for half a century, this article review aims to guide the reader into the more intricate world of multiblock copolymers by providing him/her quantitative tools to connect chemical nature, microstructure and mechanical properties.

多嵌段共聚物结构-性能关系的最新进展

多嵌段共聚物代表了一类引人入胜的材料，处于工业应用和基础聚合物科学的核心。它们通常由线性连续的不相容的“软”和“硬”片段组成，这些片段在室温下微相分离，而它们在加热时可以很容易地重新均质化。与硫化弹性体等其他橡胶基材料相比，这种热可逆特性为它们提供了决定性的优势，使它们对于更可持续的聚合物工业的发展不可或缺。除了实际机会之外，调整多嵌段共聚物的形态在对基于聚合物的系统的结构-性能关系的基本理解中发挥着关键作用。它特别有助于理解复杂的材料，如半结晶均聚物和纳米复合材料。除了半个世纪以来对明确定义的二嵌段共聚物的深入研究之外，本文还旨在通过为读者提供连接化学性质、微观结构和机械性能的定量工具，引导读者进入更复杂的多嵌段共聚物世界。
